Sobolev spaces with non-Muckenhoupt weights, fractional elliptic operators, and applications [PDF]

open access: yes, 2018
We propose a new variational model in weighted Sobolev spaces with non-standard weights and applications to image processing. We show that these weights are, in general, not of Muckenhoupt type and therefore the classical analysis tools may not apply ...

Commutators of Multilinear Singular Integrals on Weighted Herz Spaces

open access: yesJournal of Function Spaces, 2015
Suppose b→=(b1,…,bm)∈(BMO)m, TΠb is the iterated commutator of b→ and the m-linear Calderón-Zygmund operator T. The purpose of this paper is to discuss the boundedness properties of TΠb on weighted Herz spaces with general Muckenhoupt weights.

Muckenhoupt-type weights and the intrinsic structure in Bessel Setting [PDF]

open access: yes, 2023
Fix $\lambda>-1/2$ and $\lambda \not=0$. Consider the Bessel operator (introduced by Muckenhoupt--Stein) $\triangle_\lambda:=-\frac{d^2}{dx^2}-\frac{2\lambda}{x} \frac d{dx}$ on $\mathbb{R_+}:=(0,\infty)$ with $dm_\lambda(x):=x^{2\lambda}dx$ and $dx ...

Double Points Local Hardy-Littlewood Maximal Operator

open access: yesAbstract and Applied Analysis, 2013
A double points local Hardy-Littlewood maximal operator Ma,b,k,loc is defined and investigated in Euclidean spaces. It is proved that Ma,b,k,loc is bounded on Lpw when p>1 and from L1w to L1,∞w with weight function w∈Aa,b,k,loc, the class of double ...

BMO and the John-Nirenberg Inequality on Measure Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2020
We study the space BMO𝒢 (𝕏) in the general setting of a measure space 𝕏 with a fixed collection 𝒢 of measurable sets of positive and finite measure, consisting of functions of bounded mean oscillation on sets in 𝒢.

The sharp A(p) constant for weights in a reverse-Holder class [PDF]

open access: yes, 2009
Coifman and Fefferman established that the class of Muckenhoupt weights is equivalent to the class of weights satisfying the "reverse Holder inequality". In a recent paper V.

A SOBOLEV TYPE THEOREM IN VARIABLE EXPONENT LEBESGUE SPACES WITH WEIGHTS IN SIGMUND - BARI - STECHKIN CLASS

open access: yesСовременная наука и инновации, 2022
For the Riesz potential operator there are proved weighted estimates within the framework of weighted Lebesgue spaces with variable exponent. In case is a bounded do-main, the order potential is allowed to be variable as well.

Toeplitz Operators on Abstract Hardy Spaces Built upon Banach Function Spaces

open access: yesJournal of Function Spaces, 2017
Let X be a Banach function space over the unit circle T and let H[X] be the abstract Hardy space built upon X. If the Riesz projection P is bounded on X and a∈L∞, then the Toeplitz operator Taf=P(af) is bounded on H[X].
